Yasa builds 50,000th axial flux motor
In May this year, Yasa opened its fully modernised electric motor production facility in Yarnton near Oxford, offering a capacity of more than 25,000 units per year. In July, Yasa reported a new record for power density in electric motors, which the company surpassed again in October. The motor, weighing only 12.7 kilogrammes, briefly delivered a peak output of 750 kW on a test bench.
“From our first product in 2010 to powering some of the world’s most advanced performance applications, including Ferrari SF90 Stradale, Lamborghini hybrids and the next generation of Mercedes-AMG electric cars, every motor represents our pioneering spirit and engineering precision,” the company writes in a LinkedIn post.
Yasa CTO Tim Woolmer noted in a comment that the company began with a production volume of just 20 motors in 2010, and in 2025 alone, thanks to the new plant, managed to manufacture 20,000 units. “Going from 20 motors per year in 2010 to 20,000 motors per year in 2025 represents a 60% year-on-year growth every year for 15 years. Should be at 20m per annum by 2040,” Yasa’s chief engineer wrote with a laughing smiley.
Yasa specialises in particularly compact axial-flux motors – unlike the more common radial-flux motors, the magnetic field of the stator is aligned not along the radius but along the motor’s axis of rotation. This design increases power density, allowing these electric motors to be smaller overall. Because of the component layout, they often take on a disc-like form.
Mercedes-Benz AG acquired the Oxford-based company in 2021 and, two years later, presented the Mercedes-Benz Vision One-Eleven show car featuring Yasa’s axial-flux motors. This concept evolved into the AMG GT XX, which uses three of these motors and set numerous world records in August, supported by the performance and efficiency of its powertrain.
